Rain, Rain… please stay?

Although Ireland currently experiences high levels of precipitation, the world is faced with increasing environmental challenges, and water shortages, so sustainable practices have gained significant attention.

One such practice that is gaining popularity in Ireland is rainwater harvesting. Rainwater harvesting in Ireland is the practice of collecting and storing rainwater for the utilisation of various purposes such as wastewater treatment systems, septic tank systems, gardening, irrigation, and bathroom facilities, therefore reducing the reliance on conventional water sources. This eco-friendly technique has been utilised for centuries in different parts of the world and is now gaining momentum in Ireland due to its monumental environmental benefits.

How does a rainwater harvesting tank work?

Rainwater is collected from rooftops and other catchment areas using gutters and downspouts. These direct the water towards the rainwater harvesting tanks.
Before storing the rainwater, it undergoes a filtration process to remove debris and contaminants. Some systems may include additional purification methods for potable water usage.
The filtered rainwater is then stored in rainwater harvesting tanks. These tanks are typically made from durable materials such as polyethene or concrete.
The stored rainwater can be used for various non-potable purposes like gardening, agricultural irrigation, and industrial processes. Some advanced systems allow for the treatment of rainwater for drinking purposes as well.

Is rainwater harvesting legal in Ireland?

The installation of rainwater harvesting systems falls under the purview of two significant regulations: Building Regulations and Water Supply (Water Fittings) Regulations 1999. These regulations are designed to govern the construction, alteration, and maintenance of buildings to safeguard public health and the environment. According to these regulations, any non-potable water, i.e., water that is not suitable for drinking, must be kept in a separate pipework system. This clear demarcation ensures that non-potable water does not mix with the drinking water supply, mitigating the risk of contamination.
